Analysis of the installation process for the GRG design of Guangzhou GRG manufacturer's high-end decorative products

Description :

　　Ceiling wallGRG designDiverse, with a large scale of installation and uneven height, high requirements for streamline and continuity; To ensure the curvature of the ceiling and walls, installation and construction personnel must position and lay out according to the relevant requirements of the design drawings, determine the elevation and its accuracy, pay attention to the relationship between the position of the GRG board and the pipeline, and stagger the position to prevent conflicts between GRG and other pipelines. Install on-site according to the construction drawings and record the number of each material in the floor plan.

　　Based on the detailed drawing and GRG block diagram, determine the fixed position and length of the keel and suspension rod to ensure that the force on the keel and suspension rod is reasonable. And use a total station to set control points corresponding to the control points on each row of ceiling panels on the structural surface under the ceiling panel.

　　Due to the large distance between the GRG decorative panel surface and the structural panel of the suspended ceiling, a 10mm suspension rod cannot be directly used for hanging connection. Therefore, it is necessary to add channel steel as a suspension rod. The channel steel is welded to the top steel structure, and the galvanized angle steel is welded to the lower end of the channel steel. In this way, the upper end of the suspension rod is fixed on the galvanized angle steel, and the lower end is connected to the GRG panel, ensuring the length of the suspension rod. The positioning of the GRG plate at the edge is very important. After the GRG at the edge is firmly fixed, the second GRG plate is installed with this as the horizontal support point, and the other GRGs are installed in sequence. This way, during the installation process, the entire GRG will not be displaced due to the shaking of the suspension rod. Therefore, the GRG at the edge cannot be connected by a suspension rod, and must be welded with galvanized angle steel and GRG embedded parts.

　　Install the wall GRG board at the corner position first, and install it from the corner to both sides. Do not use suspension rods to fix the wall GRG board, and use auxiliary keel galvanized angle steel and channel steel for all. Galvanized angle steel is welded and fixed to pre embedded steel plates on GRG plates. For parts far away from the wall, the truss principle is used to set angle steel. The main keel is channel steel, and the vertical main keel is fixed to the wall through fixed anchor plates. The fixed anchor plates are fixed to the structural floor slab, structural beam, wall connecting beam, and ground. The horizontal main keel anchor plate is fixed to the connecting beam and welded to the vertical main keel. For walls with shapes, the working principle of triangular trusses is used to set them up. The main keel is made of channel steel and fixed to the structural wall with anchor plates. The connecting rods are made of galvanized angle steelGRG boardWelding of embedded parts inside.

　　According to the construction site positioning, locate, drill holes, and install threaded suspension rods on the conversion layer keel. According to the axis lines and elevation control lines on both sides of the suspended ceiling and the ground control points corresponding to the row of suspended ceiling panels, use a laser point projector and steel tape to guide the point to the installation position of the suspended ceiling panel. First, install the GRG shaped suspended ceiling panel on the central axis line at the installation position, level and calibrate it, and then fix the threaded suspension rod nut. Then install the next GRG shaped ceiling panel according to the height and position of the ceiling panel. After installation, use a horizontal pipe and laser level to level and recheck. Install the same row of ceiling panels in sequence, from position to position and from corners to both sides.

　　Due to the fact that the ceiling consists of a single tube lamp and a starry sky, the size of the starry sky hole position is processed together in the processing plant according to the detailed drawings, and the hole sizes are not consistent, with the connecting line at the center of the hole forming a circular arc shape. After installation, the holes must be repeatedly polished to ensure their squareness.

　　large areaGRG designThe installation must be carried out after the pipeline equipment on the ceiling is completed, such as air conditioning, air ducts, fire pipes, and maintenance channels. Ceiling lighting fixtures, air vents, sprinklers, smoke detectors, etc. must be installed in combination with the GRG shape. Before opening holes, the lines should be laid out, and the center curvature of the arc should be consistent with the GRG curvature of the ceiling, with consistent spacing between the holes, and maintain aesthetic symmetry. Install pedestrian keel inside the ceiling to facilitate the installation of starry sky and future maintenance without damaging the GRG board.
